|Abstract:||The generating function of energy counting statistics is derived for phononic junction systems. It is expressed in terms of the contour-ordered self-energy of the lead with shifted arguments, ΣA(τ, τ′)=ΣL[τ+ x(τ), τ′+ x(τ′)]-ΣL(τ, τ′), where ΣL(τ, τ′) is the usual contour-ordered self-energy of the left lead. The cumulants of the energy transferred in a given time from the lead to the center are obtained by taking derivatives. A transient result of the first four cumulants of a graphene junction is presented. It is found that measurements cause the energy to flow into the lead. © 2011 American Physical Society.|
